CLEVIS.

all whom it may, concern.'

Be it known that I, BENMMIN W. Cook, a

cit

izen of the United States, residing at Poseyville, in the county of Midland and State of chigan, have invented a certain new and useful Improvement in Olevises, of which the following is a full, clear, concise, and` exact description, reference being had to the it C- companying drawings, forming a part of this specification.

My invention relates to clevises, and particularly to a form of clevis having a pivoted link engaging a pin or upright on the main body of the clevis.

Prominent objects ol my invention are to produce the simplest possible clevis of this sort, and thereby to cheapen the cost ol manufacture of the saine, and at the saine time to prevent any reduction in the ellicie ncy, strength, durability, and ease of application and removal of the clevis.

In the clevis which I show herein for carrying out my invention, I provide a body member having a straight pin at one end, and havingl its other end curved and Aprovided with a pivotally connected link which engages said straight pin. The link and pin are so disposed and related that the link engages the end corner of the pin and requires be pressed down upon the pin so as to come in proper position upon the saine. This induces a certain amount of friction, thereby causing a firm frictional engagement between the link and pin which holds the link firmly in position. attachment as In this way all means of between the link and the pin,

are dispensed with, the frictional engagement between the two being entirely sul'licient to hold the link in place.

In the accompanying drawings, Figure l is an tio elevation of a clevis embodying my inven n, in its normal position; Fig. 2 is a view ol the same with the link partially open; Fig. 23 is a plan view of the device as shown in F ig. 1

Referring to the drawing, the clevis shown comprises a body member 1 having a curved portion 2, and a pin 3 secuied to the end of the straight portion of the body ineinbei l. The pin 5 is straight and extends vertically up O ward from the straight horizontal portion the body 1. An angular link 4 is pivotally connected to the upper end of the curved portion 2 of the body l, and is provided with an aperture 5 (Fig. 3) which is adapted to receive the pin 3 and thereby permit the link -l to be [itted over said pin 3. The aperture in the link -ft is so located that when the link is in the position shown in Fig. 2,-that is about to pass over and engage the pin 3,- the outer edge ol' said aperture will just about engage the corner (5 of the pin 3, so that in order to place the link in position, it must be pushed down upon said pin. This requires some e'll'ort, with the result that the curved portion 2 is strained a little and a very material friction engagement takes place as the link LL descends, thereby causing a .[irm cngageinent between the link and pin. '.lhe result is that the link is held. lirinly in position, so that Iiai'ring or rattling of the plow will not displace it.

The pin 3 is usually provided with a cross aperture near its upper ond, through which a small pin 7 can be inserted ill desired, but this is not necessary as the lrictional engagement between the pin and link is sullicient for all ordinary purposes.

It will be seen that the construction shown provides a strong, rigid form of clevis which can be made out of heavy substantial metal, and so made more durable and strong than if made out of lighter metal or bent wire. The body 1, it will be seen, can be readily cast with the pin 3 integral with it and the link can be separately east and attached to a hooked end of the body. By making the pin 3 straight, the need of bending the saine is done away with and the p iii can be made as thick, strong and stout as desired, and when cast can be cast in the inost desirable way,M that is straight, -and at the saine time the proper amount of friction is secui'ed to insure the link being held lirinly in position, by arranging the link and pin as hereinbel'ore set forth, which could ,not be done if the pin were bent or crooked near it's end if the device was made out ol heavy metal for heavy work, because there would not be sullicient elasticity or give to the heavy metal to enable the link to pass the crook and. slide down the pin.

IVhat I claim as my invention is :g-

A clevis comprising a metal body having one end bent and having its other end promy name this 31st day of January A. D., vided With a continuously straight pin and 1907.
